Hexagonal 316 stainless steel reducing bushing with male and female NPT threads

Value Brand

Value Brand 1RTW4 Hex Reducing Bushing 316 Stainless Steel 1-1/2 in x 1 in

SKU CH-HNNG-VNA8S

Hex reducing bushing adapts 1-1/2 in male NPT to 1 in female NPT, 316 stainless steel, Class 3000 rated to 3000 psi at 100°F and 2500 psi at 350°F, ASTM-A-182 and ASME B16.11

  • 316 stainless steel resists corrosion in harsh environments
  • Hex flats enable secure wrench tightening for leak-resistant joints
  • Reduces 1-1/2 in male NPT to 1 in female NPT for size adaptation
  • Class 3000 rating handles up to 3000 psi at 100°F
  • Meets ASTM A182, ANSI/ASME B1.20.1 and ASME B16.11 standards

Product Identity

Value Brand 1RTW4 is a hex reducing bushing made from 316 stainless steel that connects a 1-1/2 inch male NPT thread to a 1 inch female NPT thread. It is rated for class 3000 service with a maximum pressure of 3000 psi at 100°F and 2500 psi at 350°F. The fitting conforms to ASTM-A-182 and ASME B16.11 standards.

Suitability

This bushing suits installers who need a corrosion-resistant transition between different pipe sizes in high-pressure water, oil or steam lines. It is not for systems that require a larger female opening or a different thread standard such as BSPT.

Critical Specification

The male NPT size of 1-1/2 inch and female NPT size of 1 inch determine whether this bushing matches the existing piping. Verify both nominal sizes and the class 3000 pressure rating before ordering.

Highlights

  • 316 stainless steel resists corrosion in harsh environments
  • Hex flats enable secure wrench tightening for leak-resistant joints
  • Reduces 1-1/2 in male NPT to 1 in female NPT for size adaptation
  • Class 3000 rating handles up to 3000 psi at 100°F
  • Meets ASTM A182, ANSI/ASME B1.20.1 and ASME B16.11 standards

Questions about this item

Should I choose the 1-1/2 in to 1 in hex reducing bushing or a different size for my piping?

This fitting adapts a 1-1/2 in male NPT thread down to a 1 in female NPT thread. Select it only when you need to reduce from that specific larger male size to the smaller female size.

What does the Class 3000 pressure rating mean when the bushing is installed in a system?

Class 3000 allows up to 3000 psi at 100°F and 2500 psi at 350°F. The rating drops as temperature rises, so design your system pressure below the limit for the actual operating temperature.

The bushing uses NPT threads — what standard do they follow and what does that cap in practice?

Threads conform to ANSI/ASME B1.20.1, which defines taper, pitch and engagement for leak-resistant sealing. The standard caps the maximum thread size and tolerance, so the joint will not exceed the Class 3000 pressure limits.
